MIC-200-IR3 Three-band infrared flame detector
The MIC-200-IR3 three-band infrared flame detector is a reliable and high-performance flame detector. It uses advanced flame analysis and recognition technology to quickly respond to infrared radiation in a fire and has the highest false alarm immunity . The MIC-200-IR3 detector contains three narrow-band infrared sensors (4-6 microns) and optical filters, which have high sensitivity to carbon dioxide emission spectra (4.4 microns), which can effectively eliminate interference and achieve greater distances.
Features of three-band infrared flame detector:
1. Developed by the principle of three-wavelength infrared
detection, it has extremely high immunity to false alarms;
2. High-speed response to flame;
3. Built-in high-performance microprocessor;
4. Excellent anti-radio frequency and electromagnetic interference
performance;
5. Reliable system fault self-diagnosis function;
6. Two output modes of three-wire current loop and relay are
optional;
7. Patented signal processing algorithm to minimize the possibility
of false alarms;
8. Multi-level sensitivity settings to meet the different needs of
more occasions;
9. Easy to install, the detection angle can be adjusted by 360°;
10. ExdⅡ CT6 explosion-proof grade, suitable for zone 1 and zone 2
hazardous locations.
